Juan Manuel García-Manso and his associates have recently published a study on the effect of different types of stretching on muscle response using tensiomyography. More specifically, tensiomyography was used to examine the changes observed in the response of the biceps femoris muscle of the dominant leg of ten young female gymnasts after performing two different stretching protocols: contract-relax (CR) and static-stretching (SS). The results revealed a change of muscle response immediately after warm-up: increased velocity of deformation, stiffness, holding time and reduced relaxation time. The changes were most evident in the first three minutes after applying the two stretching protocols, being more evident in CR than in SS. The results suggest that athletes who include stretching in their warm-up will find the post warm-up mechanical response less impaired after the first three minutes and more so when using the techniques based on working with static-stretching, compared to techniques based in contract-relax.
